A new paper from Richard and Cory reports the two-electron reduction of a bridging pyridine. Great work from Team Pyridine!

Congratulation to Cory, whose Communication recently appeared in J. Am. Chem. Soc. This paper describes the surprising finding that after our reduced iron species cleave the N-N bond of N₂, they can rapidly reform the bond to produce N₂ again. These results demonstrate that our multiiron complexes lower the activation barriers to both the cleavage and formation of N-N triple bonds. Great job, Cory!

We have now shifted into freshly renovated labs in the Kline Chemistry Laboratory. The space is really nice, and kudos to the building team as well as to the eternally patient students who tolerated two lab moves within a year. We are now making progress at full speed in the new space!

Karen Chiang's paper on the details of reactivity of iron complexes with N₂ was published in Chemical Science. This paper is a great demonstration of how multiple iron atoms work together to bind N₂ effectively.
